August Moon at 2nd Apogee

   For the second time this month our Moon reaches apogee, (greatest distance from Earth), on Wednesday August 30th. At that time the Moon will more or less be at a distance of 31.69 Earth diameters (404,308 km or 251,225 miles) from the Earth.

   On the day of the apogee the 10-day old waxing gibbous Moon rises during mid-afternoon and is about 7o from Saturn and around 10o degrees from the reddish star Antares in Scorpius the Scorpion.

   Does our Moon actually go around the Earth as the above graphic shows? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*
